The teacher must have aptness for his work. He must have the wisdom and tact required in dealing with minds. However great his scientific knowledge, however excellent his qualifications in other lines, if he does not gain the respect and confidence of his pupils, his efforts will be in vain. [Sidenote: _Administrative Ability_] Teachers are needed who are quick to discern and improve every opportunity for doing good; those who with enthusiasm combine true dignity; who are able to control, and “apt to teach;” who can inspire thought, arouse energy, and impart courage and life. A teacher’s advantages may have been limited, so that he may not possess as high literary qualifications as might be desirable; yet if he has true insight into human nature; if he has a genuine love for his work, an appreciation of its magnitude, and a determination to improve; if he is willing to labor earnestly and perseveringly, he will comprehend the needs of his pupils, and, by his sympathetic, progressive spirit, will inspire them to follow as he seeks to lead them onward and upward. [Sidenote: _Difficulties_] [Sidenote: _Sympathy and Insight_] The children and youth under the teacher’s care differ widely in disposition, habits, and training. Some have no definite purpose or fixed principles. They need to be awakened to their responsibilities and possibilities. Few children have been rightly trained at home. Some have been household pets. Their whole training has been superficial. Allowed to follow inclination and to shun responsibility and burden-bearing, they lack stability, perseverance, and self-denial. These often regard all discipline as an unnecessary restraint. Others have been censured and discouraged. Arbitrary restraint and harshness have developed in them obstinacy and defiance. If these deformed characters are reshaped, the work must, in most cases, be done by the teacher. In order to accomplish it successfully, he must have the sympathy and insight that will enable him to trace to their cause the faults and errors manifest in his pupils. He must have also the tact and skill, the patience and firmness, that will enable him to impart to each the needed help,—to the vacillating and ease-loving, such encouragement and assistance as will be a stimulus to exertion; to the discouraged, sympathy and appreciation that will create confidence and thus inspire effort. [Sidenote: _Social Relation_] Teachers often fail of coming sufficiently into social relation with their pupils. They manifest too little sympathy and tenderness, and too much of the dignity of the stern judge. While the teacher must be firm and decided, he should not be exacting or dictatorial. To be harsh and censorious, to stand aloof from his pupils or treat them indifferently, is to close the avenues through which he might influence them for good. [Sidenote: _Partiality_]
